Ph 2 trial of botensilimab (BOT), balstilimab (BAL) & agenT-797 in GEJ cancer shows 77% DCR and long-term survival beyond 20 months in heavily pretreated patients

“These findings illustrate the mechanistic synergy of agenT-797 with botensilimab and balstilimab in this PD-1 refractory setting,” said Dhan Chand, Ph.D., Vice President of Research at Agenus. “The induction approach promoted significant intratumoral infiltration of T cells and dendritic cells, the formation of organized tertiary lymphoid structures in on-treatment biopsy tissue from a patient with durable benefit, and activation of peripheral CD4 and CD8 T-cell populations. These changes are consistent with immune priming and tumor immune reprogramming, providing a biological rationale for the improved progression-free survival observed with the induction strategy.”
